In the small clearings and settlements on the lakes a number 

 of weeds and other introduced plants have appeared. This was 

 an extremely interesting part of the flora to me, and I therefore 

 made as full a list as possible of the species observed. The in- 

 vading army was then small in number and few in species, but is 

 likely here as elsewhere to more than hold its own as long as the 

 clearings are open to the sun. I mention a few of these invaders 

 to show how our common weeds travel in the footsteps of man : — 

 Ranunciilits acris ; Capsella Bursa-pastoris ; Stellaria media ; 

 Spergiila arvensis ; Tr if olittni prate use, and T. repens ; Sediun 

 TelepJiiiiin ; Achillea Millefoliinn ; Chrysantlienmm Leucanthe- 

 nmm ; Taraxacum officinale ; Tanacetum vulgare ; Cniciis ar- 

 vensis and C. lanceolains ; Plantago major ; Galeopsis Tetrahit; 

 Polygonum Persicaria ; and Rnmex Acetosella. All these 

 species were collected at the Upper Dam, except Spergnla arven- 

 sis, which was seen only at Indian Rock, some miles farther 

 north. Most of them, however, appeared as well in other in- 

 habited clearings, and often about the logging camps in the 



w 



oods. 



I have not spoken of the trees and shrubs, for the species 

 observed were those that any one would expect to find in the 

 northern woods. The whole region is much devastated by the 

 lumbermen, and little pine have they left behind them. The 

 poplar and the spruce are now being attacked, and I suppose in 

 time this country will lose much of the wild beauty that is now 

 one of its greatest charms. EDWARD L. Rand.

These singular plants, with their variously colored bracts and 

 comparatively inconspicuous flowers,' are very numerous in the 

 West, and exceedingly variable. In Custer County, Colorado, 

 we have at least three species — possibly more, w^hile each one of 

 these presents interesting varieties or forms. About West Clifi", 

 rather below 8,000 feet alt., one finds in the meadows and on the 

 prairies scarlet and pale yellow species. The scarlet-bracted 

 species, which grows mainly on dry land, is C. Integra^ Gray ; 

 the other taller, and with pale yellowish bracts, is C, pallida
